HUB-LINER FOR LOCOMOTIVEJOURNALS.

To all whom it may concern Beit known that I, LUTHER K. SMITH, a citizen of the United States, residing in Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Hub- Liners for Locomotive-Journals, of which the 'following is a Specification.

My invention relates to journal boxes especially adapted to the journals ot' locomotive driving wheelsA and other similar heavy journals and has for its object to produce a new and improved hub liner for use in such structures.- The said devices are lillustrated in this application in connection with a journal bearing of the character of that illustrated in Patent No.-941,661,'issued t'o me November 30th, 1909, but they are not confined in use to a journal bearing of this description.

My present invention is a division of a 1` former application tiled by me February 2nd, 1912, Serial-No. 674,861.

rI`he object of my invention is to provide a structure which shall be simple in construction and Shall be economical, durable. and eiiicient in use and a most important object to be accomplished is that the parts mentioned which require adjustment and replacement in use may be so replaced without dismantling a locomotive engine, if they are applied thereto, or sending; the same to the repair-sliep whereby the usefulness of the engine is greatly increased.

In achieving the foregoing objects my in vention consists in the production ot a hub liner which is adapted to be inserted between the bearing and the hub of a. wheel and which may be inserted in place or removed therefrom without dismantliiur thc engine or taking* the journal box otlE he journal or away from under the engine.

In the accon'ipanyiup, drawing,r illustrating a desirable form in which my invention may be embodied, Figure 1 is a tace View of a journal bearing to which my invention is applied. Fig. 2 is a vertical section thereof onV the line 2-9., Fig. 1, lookingr toward the right. Fig. 3 is a rear yelevation ot' a journalvbearing partly broken. Figs. 4, Vi and 6 are detail views of the liub .liner forming: part otl my present invention. l

I have for convenience ot miderstanding Specification of Letters Patent. original application filed February 2, 1912, serial Nemesi.

Patented Oct.'7, 1913. Divided and this application filed April 23,

Serial No. 692,671.

illustrated my invention as applied to a journalbearing ofthe construction shown in my Patent No. 941,661, alth-.fzugh the invention not nf-ccssarily limited in its application to this type of journal hearing. The general teaturcf-i ot' consti-tuition ot' the journal bearingl referred to are fully described in said 'patent and application, Serial No. 674,861, and t'or the sake ot brevity are emitted here.

The construction of `grease holder and dust guard illustrated in the drawings'is not claimed in this application, but is claimed in arseparatc application tiled by me April 23, 1912, Serial No. (392,672.

I have also illustrated a wedge C which is employed tor the purpose otl taking up the wear between the journal box and the pedestal jaws and preventing lateral n'iovcinent ot the journal box. The construction of wedge and its associated parts is not herein claimed, but is claimed in my said application, Serial No. (574,861, filed February 2, 1912.

The foregoing parts form no part of the invention in this present application.

I will now proceed to describe the particiilar points to which theclaims are directed. j

In Figs. 4, 5 and 6 I have illustrated the improved hub liner designed by me removed from the Vjournal box. This hub liner is in two partsavliich are thc same in construction willi the exception that they are made right, and left. One of Such hub liners is illustrated in detail in said figures, and is there let tercd I. Said huh liners are made substantially in the are ot' a circle, and are provided with peripheral [langes which are received in corresponding grooves vf' in the body l. These grooves extend to the lower iniierjlace of the body where they open tor the reception of the hub liii'ei's. At the upper portion the end ot' the said grooves is closed by the body ati2 forming au abutment which limits the upward movement ot' the hub liners. llach hub liner is provided with an inwardlyY projectingr stud i" which is received in a correspondingl recess 1'* of the body (see Fig. 'i'tie cellar block L2 when moved to its eX- treme forward adjustment passes beyond the said studs 3 and holds the hub liners in place (Fig. 2). The brass b likewise overlaps the inner edge of the hub liners when in position in the journal box and assists in holding them in place, and forms a support therefor. rThe wearing face 5 of the hub liner is formed of a plate of suitable bearing metal, such as tin, properly fixed thereto and this may be renewed when desired. Said hub liner possesses particular advantages in hat the hub liner can be removed for the purpose of repairing or refacingl the bearing face withouttalting the journal box oti' from the journal or ont from under the engine. To remove the hub liner it is only necessary to pull the cellar block 722 and the journal brass Z2 out of the box far enough to clear the inside face of the liner and the studs 3, whereupon the said hub liners may easily be removed by simply sliding them out of the. grooves z. The eellar may be moved by taking ott nuts au on bolts m5 whereby lugs af* are freed. The removing of the cellar permits the brass to be also moved. It isnot necessary to dismantle any part of the engine in order to accomplish this purpose. The grooves 2f. for the reception of the hub liners are situated near the face of the body B and when the cellar block b2 and the brass 7) are slightly withdrawn the hub liners I are easily inserted in place by taking` them one at a time and introducing the upper edge of the flange i in the lower end of the groove e". The lug i3 will then pass Within the recess z" and this hub liner may be held in place while the opposite hub liner is similarly inserted in its groove and recess. '.lhe brass and cellar block being then again adj usted to their position the hub liners will be firmly held in `place.

Means are provided for lubricating the hub-liners comprising ports 7) by which lubricantis conducted from the reservoir 7) to the said hub liners.

lVhile T have described with great partienlarity the detail features of construction of the said invention, it will be ap )arent that the invention is not in all things limited to such particular details or structural formation, an' that equivalent devices may be employed and changes made therein within the limits of the appended claims.
